[jira] [Created] (FLINK-16844) Support retract message for StreamExecGroupWindowAggregate in blink planner

Benchao Li created FLINK-16844:
----------------------------------

             Summary: Support retract message for StreamExecGroupWindowAggregate in blink planner
                 Key: FLINK-16844
                 URL: https://issues.apache.org/jira/browse/FLINK-16844
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / Planner
            Reporter: Benchao Li


Currently the `WindowOperator` in blink planner actually supports retract messages, however in StreamExecGroupWindowAggregate, we throws exception if input is retract. IMO, we can remove this check and let `StreamExecGroupWindowAggregate` support retract messages. This will enhance the ability of blink planner very much.
